TYPE-CONTAINING CHANNEL.

SPECIFICATION forming part of Letters Patent No. 634,214, dated October3, 1899.

Application filed June 22, 1896. Serial No. 596,372. (No model.)

' SON and ABBOT AUGUSTUS Low, citizens of the United States, residing inthe city of New,

York, (Brooklyn,) in the county of Kings and State of New York, haveinvented certain new and usefullmprovements in Type-Containing Channels,of which the following is a specification sufficient to enable othersskilled in the art to which the invention appertains to make and use thesame.

Our invention relates to type containing channels designed for use inconnection with the form of type-case set forth in-our application forpatent, Serial No. 602,136, filed August 8, 1896; and the inventionconsists in the special construction and arrangement of partshereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation of the right-handside of our improved channel; Fig. 2, a front elevation of the sameadjusted to the narrowest width; Fig. 3, a top viewiof Fig. 2; Fig. 4, afront elevation adjusted to the fullest width; Fig. 5, a top View ofFig. 4. Fig. 6 is a longitudinal section on plane of line 6 6, Fig. 1.Fig. 7 is an elevation of the inner side of the lefthand channel-wall.Fig. 8 is a rear View of the same. Fig. 9 is a rear view of therighthand wall; Fig. 10, a front View of the same. Fig. 11 is a top Viewof the left-hand side wall; Fig. 12, a similar view of the right-handside wall.

The channel is made in two parts A and B, each constituting a side walland apart of the spine. The rear flanges a b, which constitute thespine, are formed upon the opposed inner surfaces of the plates or sidewalls A B and are preferably of equal thickness,

each representing one-half the width of the spine when the parts areadjusted for the narrowest types, as illustrated in Figs. 2 and 3. Thelower end of one side wall is formed with the laterally-projectingtype-floor c, extending across the channel and under the lower end ofthe opposite side wall. This typeplatform 0 is of a width sufficient toafford a support for-the wid'est types when the parts are adjusted withrelation thereto. The typeplatform 0 may obviously be formed on eitherone or the other of the side walls A B. The

I portion ofthe spine on one side plate ends a considerable distanceabove the position of the type-floor c in order to leave the space orslot at for the passage of the type-forwarder when the channel isinserted in the type-setting apparatus. The separation or adjustment ofthe side walls of the channel with relation to each other is effected bymeans of screws 8, by which the portions of the spine are held together,washers 10 being interposed between the spines a b when it is desired towiden the channel.

What we claim as our invention, and desire to secure by Letters Patent,is

1. As an article of manufacture a type-containing channel consisting ofthe side Walls A, B, having the flanges a, 1), formed with femalescrew-threads for the reception of the headless coupling-screws s, andsaid couplingscrews 5, the whole arranged and operating substantially inthe manner and for the purpose described.

2. As an article of manufacture a type-containin g channel consisting ofside plates each formed with a portion of the common spine and withfemale screw-threads for engaging with male screws, one side plate beingformed at one end with a transverse type-supporting shoulder or flangeof a width equal to the maximum width of the channel, and screws forsecuring the parts rigidly together substantially in the-manner and forthe purpose described.

3. As an article of manufacture a type-containing channel consisting ofside plates each formed with a portion of the common spine and withfemale screw-threads for engagement with male screws, one side platebeing formed at one end with a transverse type-supporting shoulder orflange of a' width equal to the maximum width of the channel,spacingwashers interposed between the opposed portions of the spine, andscrews for securing the parts rigidly together, substantially in themanner and'for the purpose described.

4. As an article of manufacture a type-containing channel consisting ofside plates each formed with a portion of the common spine and withfemale screw-threads for engagement with male screws, one side platebeing formed at one end with a transverse type-supporting shoulderorfiange of a width equal to idly together substantially in the mannerand the maximum Width of the channel, the porfor the purpose described,
